问题:

Android开发,用Kotlin语言。编译时报错了,如下:

FAILURE: Build failed with an exception.

  • What went wrong: Execution failed for task ':app:processDebugResources'.

A failure occurred while executing com.android.build.gradle.internal.res.LinkApplicationAndroidResourcesTask$TaskAction Android resource linking failed com.example.activitytest.app-mergeDebugResources-30:/layout/file_store_layout.xml:20: error: attribute layout_constraintStart_toStarOf (aka com.example.activitytest:layout_constraintStart_toStarOf) not found. error: failed linking file resources.

  • Try:

Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights. Get more help at https://help.gradle.org.

Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

For more on this, please refer to https://docs.gradle.org/8.7/userguide/command_line_interface.html#sec:command_line_warnings in the Gradle documentation.

请分析原因,并解决问题。

答案:

从错误信息来看,编译失败的原因是因为在 file_store_layout.xml 文件中使用了一个不存在的属性 layout_constraintStart_toStarOf。这个属性名应该是拼写错误,正确的属性名应该是 layout_constraintStart_toStartOf

以下是解决问题的步骤:

  1. 打开 file_store_layout.xml 文件。
  2. 找到第20行(错误信息中提到的行)。
  3. layout_constraintStart_toStarOf 修改为 layout_constraintStart_toStartOf

修改后的代码示例:

<androidx.constraintlayout.widget.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!-- 其他布局代码 -->

    <TextView
        android:id="@+id/textView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        android:text="Hello World!" />

    <!-- 其他布局代码 -->

</androidx.constraintlayout.widget.ConstraintLayout>

确保所有的约束属性都拼写正确,例如:

  • layout_constraintStart_toStartOf
  • layout_constraintEnd_toEndOf
  • layout_constraintTop_toTopOf
  • layout_constraintBottom_toBottomOf

完成修改后,重新编译项目,问题应该会得到解决。

如果问题依然存在,请检查以下几点:

  1. 确保 ConstraintLayout 的依赖已经正确添加到 build.gradle 文件中:
dependencies {
    implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
}
  1. 确保所有的 XML 命名空间声明正确:
xmlns:app="http://schemas.android.com/apk/res-auto"

完成这些检查后,再次尝试编译项目。如果仍有问题,请提供更多的错误信息以便进一步分析。
